15. SYNANDRA Nutt. Gen. 2: 29. 1818. 



An annual or biennial, somewhat hirsute, simple or little branched herb, with long- 



petioled ovate cordate crenate leaves, and large whitish flowers in a terminal leafy-bracted 



spike. Calyx campanulate-oblong, membranous, deeply 4-cleft, inflated in fruit, faintly and 



irregularly veined, the lobes narrowly lanceolate, the two upper shorter than the lower. 



Corolla much longer than the calyx, its tube narrow below, much expanded above, 2-lipped; 



upper lip concave, entire; lower lip spreading, 3-lobed. Stamens 4, didynamous, ascending 



under the upper lip of the corolla; filaments villous; anthers glabrous, 2-celled, the sacs 



divaricate, the contiguous ones of the upper pair of stamens sterile and connate. Ovary 



deeply 4-lobed ; style unequally 2-cleft at the summit. Nutlets ovoid, smooth, sharply angled.

Stem rather slender, erect or ascending, weak, 

 l-2i long, striate. Leaves thin, the lower and 

 basal ones broadly ovate, or nearly orbicular, pal- 

 mately veined, acute or obtuse at the apex, deeply 

 cordate at the base, the blade 2-4' long, and com- 

 monly shorter than the petiole ; floral leaves sessile, 

 ovate or ovate-lanceolate, acute or acuminate, the 

 flowers solitary in their axils, the uppermost leaves 

 very small ; calyx hirsute, its lobes about as long as 

 the tube; corolla l'-lj' long, showy, the lower lip 

 with purple lines. 



Along streams and in wet woods, Ohio to Illinois, 

 Virginia and Tennessee. Ascends to 3,500 ft. in Vir-

 limb mostly equally 5-toothed. Corolla-tube usually with a woolly ring within, shorter than 

 or exceeding the calyx, the limb strongly '2-lipped ; upper lip erect, concave, arched or some- 

 times keeled, entire or emarginate ; lower lip spreading, 3-cleft. Stamens 4, didynamous, 

 ascending under the upper lip of the corolla, the anterior pair the longer and their filaments 

 with hooked appendages at the base; anther-sacs divergent. Ovary deeply 4-lobed; style 

 subulate, 2-cleft at the summit, one of the lobes smaller than the other. Nutlets ovoid, 

 glabrous, or pubescent above. [Greek, mullen, in allusion to the thick woolly leaves of some

 densely many-flowered ; bractlets subulate, ciliate- 

 hirsute or nearly glabrous; calyx s"-6" long, its 

 teeth setaceous with a broader base, spreading; 

 corolla io"-I2" long, pale purple or white, twice
